Re: Intense heat here has made my accordions unplayable.
Where were you keeping those accordions for them to warp like that? How'd the wax do? Wax should have melted before anything else went wrong in those kinds of temperatures, but only if you were keeping them in a hot vehicle or something. I once had a problem with an Acadian. Rusted the reeds because I played the accordion too many times outside from air conditioner inside to hot humid conditions outside. Played it too many times near the dirty saltwater of Holly Beach too for hours on end.
